C++:
VstIntPtr function dispatcher(AEffect* e, VstInt32 opcode, VstInt32 index, VstIntPtr value,
void* ptr, float opt);
Delphi:
function dispatcher(e: PAEffect; opcode, index: VstInt32; value: VstIntPtr; ptr: pointer;
opt: Single): VstIntPtr; cdecl;
always returns 0, unless otherwise defined.
all string-pointers points to zero terminated strings.
e[ ]: = plugin receives as entry parameter
x[ ]: = plugin returns to host
dispatcher() function using opcode 28:
28. effGetNumProgramCategories
28. effGetNumProgramCategories
>= VST2.0 ... deprecated in VST2.4 @see AudioEffectX::getNumCategories()
no arguments, this is for dividing programs into groups (like GM)
x[return]: 1 when there is no real program categories
C++ method:
VstInt32 AudioEffectX::DECLARE_VST_DEPRECATED(getNumCategories) ()
Delphi method:
function AudioEffectX.getNumCategories: VstInt32;
